Hot With A Good Chance Of Storms

It should be a nice cool day -- at least compared to Monday's scorcher, when the mercury shot up to 100 degrees in Fort Lauderdale.

In reality, it's still going to be hot and muggy.

Today's forecast calls for mostly cloudy skies, afternoon temperatures in the low 90s and evening lows in the upper 70s.

There also is a 50 percent chance of showers and thunderstorms.

Wednesday should be slightly cooler yet, with possible afternoon storms.

Heat index: You ever wonder how meteorologists compute the heat index, or feels-like temperature? Here's an explanation, courtesy of my colleagues at the Orlando Sentinel:

The heat index is a combination of the temperature and humidity used to give people a better idea of what the outdoors really feels like, said meteorologist Arlena Moses of the National Weather Service.

Monday?s temperature was about 98 degrees (in Orlando), but factor in humidity and it felt like 107. Evaporation is the key to staying cool, Moses said, but the more moisture in the air, the less sweat is evaporated.
